The highly efficient Capillary Electrophoresis (CE) is a method used for the separation, identification, and quantitative analysis of many compounds contained in food products. Owing to the diversity of techniques offered by CE, this method can be used to determine contents of both the high-molecular compounds, such as proteins or DNA fragments, and the low-molecular compounds: amino acids, carbohydrates, vitamins, flavonoids, inorganic ions, and organic acids. The use of this method and its techniques in food control laboratories can essentially facilitate the verification of the declared and real composition of food products.
